Marzocchi Bombers Z3.5

[jdubbya]

Hi all, nice to meet you - I’m new here.

I’ve just completed a build of a 2000 Specialized Rockhopper FS with majority original parts - please take a look at my photos.

I managed to source a great set of 2001 coil/oil Z3.5 Marzocchi Bombers that were originally sold with the Specialized P3. They are a perfect match colour-wise and in great condition. Being a heavier rider, what options do I have to increase stiffness? I’ve set pre-load as far as it will go but they’re still a little bouncy when riding uphill. Would a heavier weight oil help?

Thanks for any input.

Weigth => Use a matching spring.
Oil => Damping

I'm no expert but most of the Marzocchi forks are easy to work on and parts are available. As above, you probably need a stiffer spring if you're a heavier rider.
Heavier oil will slow the compression and rebound but you really need to get the spring right first then tweak the damping.
A quick google seach should find you a manual with diagrams and instructions for working on them.
And welcome - bike looks great!

Thanks for the responses - much appreciated. I’ve found the right manual - any idea where I’d source springs in the UK?

Cheers

Check this .... https://www.ebay.co.uk/sch/i.html?_...filtering&_ssn=slk.r171&_oac=1&_nkw=marzocchi that's a well known seller Piotr from PL selling on Ebay UK.

Will be a little tricky to find correct springs, you need so find out serial numbers and details (hard, x-firm, may be springs colour) from the net/manuals/charts.

Try to ask parallel @ Facebook Marzocchi group https://www.facebook.com/groups/retromarzocchimtb - I believe it is the most active Marzocchi group.

I did some harder 100 and 130 mm travel springs for 30mm stanchion forks but down't know for sure it will fit.

That’s great - I’ll give them a shout. Thanks again.
